So my friend was given an R4 but we're not really sure what kind of R4 it is. He just gave it to me so I can put the firmware and stuff. The sticker says R4i SDHC Revolution for DS (NDSI/NDSL/NDS) and it's a gold sticker. My friend lost the box so he can't really remember what exactly it is.

Also, is this flashcart compatible with firmware 1.4.1? What files do I need to download? Will the Wood firmware be compatible with this?
